肥美 (féi měi) is an adjective describing food—especially meat, fish, or poultry—that is both plump (indicating richness and tenderness) and delicious (suggesting full, savory flavor). The character 肥 literally means 'fat' or 'plump', evoking juiciness and marbling; 美 means 'beautiful' or 'delicious', emphasizing sensory appeal and high quality. Together, they form a compound that conveys abundance, freshness, and culinary excellence—not just fattiness in a negative sense, but desirable, well-fed, succulent qualities.

This term is commonly used in descriptions of livestock, seafood, or wild game, especially in contexts emphasizing natural rearing or seasonal peak condition. It often appears in food writing, agricultural reports, and restaurant menus to highlight premium ingredients. While it can occasionally describe land ('fertile and lush'), its primary and most frequent use is for edible animals or their meat—never for people or abstract concepts.
